What happened: The Buffalo Sabres acquired defenseman Olen Zellweger to help replace the departed Bowen Byram. Buffalo also added Louis Crevier and brought back veteran forward Conor Sheary.
Why it matters: Zellweger provides a left-shot option on the blue line after Byram was moved to acquire the fourth overall draft pick. Sheary brings familiar depth to the forward group, having previously played for the organization.
By the numbers: Zellweger recently signed a three-year extension with a $3.1 million average annual value. Sheary returns on a one-year, $850,000 contract.
What to watch: Buffalo will evaluate its revamped defensive pairings and forward depth as training camp approaches for the 2026-27 season.
